According to People, Pebe Sebert said she'll be going to rehab at her daughter's urging, citing "post-traumatic stress disorder." You might remember that Sebert was very vocal about her daughter's bulimia after news broke of Ke$ha's stint in rehab, blaming super producer Dr. Luke for Ke$ha's body image issues. Sebert further explained that Dr. Luke's intense criticism of Ke$ha's body put whole lot of stress on the family: "This whole Dr. Luke thing has almost torn our family apart and taken over my life, and Ke$ha wants me to heal along with her."
